ELECTRICAL SPECIFICATIONS

REFERENCE CONDITIONS

Accuracy is given in the following reference ranges:
- temperature: +23°C ± 3°C
- relative humidity: 45% to 75% RH
- battery voltage: 6 V ± 0.1 V
- position of the conductor: centred in the clamp
- DC magnetic field: the earth's field (< 40 A/m)
- external AC magnetic field: none
- external electrical field: none
- frequency of the AC component of the signal: 45 Hz to 65 Hz
The accuracy is expressed as a % of the reading (± %R) and in measurement counts
(± count).
NB: Some reference conditions are listed for specific functions, if applicable, with the elec-
trical specifications of the functions.

AC AND DC CURRENTS

Specific reference conditions
- on AC: sinusoidal signal
- on DC: AC component 0.1% of DC signal with corrected zero
